SAP PP Questions and Answers

SAP PP Questions and Answers

What are the cutover activities followed for PP module?
I am listing some cut over activities to be followed (for PP - Discrete Manufacturing).
Production Planning / Master data:
For Production planning, only master data shall be migrated to SAP. In the 1st Stage, there is no master data. Following is the master data elements relevant for PP:
- Bill of materials
- Routing.
- Work Centres.
Transaction data:
As of the cut off date, ideally there should not be any work in process. All the open production orders should be closed and semi finished goods should be dismantled and should be added to Raw materials. This strategy should be followed for all production orders where lead time to complete the production order is not large.
Since, the production orders are for longer duration and it is not possible to dismantle the product and add it to inventory, following can be the strategy for migrating the data to SAP:
- Create a material master for the work in process and set the standard price as the cost incurred for that product (ie. Work in process)
- Create a bill of material (which will be used only for this production order) including this material and other materials still to be consumed.
- Create Routing for rest of the production process.
- Bring the work in process material into inventory as of the cut off date.
- Create the production orders in SAP for the Work in process and issue materials to production order.
Complete the production process after the cut off date of the project.

What happens to planned after it has been converted into production order?
When you convert Planned order to Production order. the planned order are offset by production order. Reference of planned order can be seen in the production order.

How to attach a drawing for a material to BOM? Is it possible?
Yes, you can attach a drawing.
First create a document using Transaction Code "CV01N - Create Document".
Attach your drawing in that document.
The system will generate a document number. Assign this document in the BOM with item category D.

Report in Long Term Planning - You use long term planning for your customers, what they need are very simple, just to calculate future requirements for 1 or 2 years.
Are there any reports in SAP to list of material requirement from LTP?
You need a list of material requirement from long term planning result for each item.
Use MS70 then use MCEC.

Scheduling planned order - How can you get planned orders scheduled so that you can do capacity leveling?
MD11 and then Schedule works fine but ideally you would want the the planned order scheduled automatically on creation? You have tried setting up an action to schedule the orders but cannot get that to work either.
When running MRP, try selecting "2" in the scheduling box this will bring planned orders into CM01 and CM21

Capacity planning CM01 - When you run capacity planning T-code: CM01, you found the plan orders are not included in the pegged requirement, you checked the profile, the check box for order and plan order are all actived.
Guess that planned orders have been created without capacity requirement indicator in MRP ("2" - Lead Time scheduling), if this is the case, then when converted to process orders they will have impact on the Resource. If you want to see them as planned orders, re-run the MRP or change in every planned order, going to the Menu: Edit --> Scheduling
Another couple of possibilities are to do with the routing/work centres used and whether it isactually calculates consumption of capacity of the category at the work centre being displayed in CM01 (it might consume a capacity pool or it might not consume the category).

MPS in Backgound/Online - You want to run MPS for a plant either online or in the background, but you do not get any results. If you run MPS for a single material/plant, then everything is 100% OK.
You need to run a planning file and a consistency check first, transaction OMDO and MDRE respectively you'll need to set up two jobs to do it but it is straight forward, once you've done this set up the background job for MPS to run and do it in NEUPL first time round and then change to NETCH after that.

What is the output of MPS run?
From MPS run you plan the materials which are of 'A' type in the abc analysis (80% dollar value) that have to be planned before hand.
MPS is also a type of MRP only in which components just below the materials on which MPS run is taken place, are planned.

Table for production order status - What is the table for finding status (for Ex TECO ed prodn orders). We are not able to find from AFKO and AFRU tables the status of production orders or at least the link tables if known can be mentionned. You are unable to link the structure caufvd and IOHEADER WITH AFKO and AFRU.
JEST is the table.

Data dictonary table for SOP planning data - You are using Standard SOP (Info structure S076), in which table can you see the planning values that you maintained in MC93 transaction?
You looked under table "S076" and did not see any values there.
Use T.Code MC95 to display your entries under the version which maintained the the table S076.

Production order operation's component allocation - How does SAP know that an operation has components as indicated by the component allocation indicator? Tcode CO08.
Component allocation is done via routing maintenance or BOM maintenance for the assembly. This is master data maintenance. As soon as a PO is created, the master data is read into the PO.

How to delete groups of products?
How to delete a group of products that was created in screen MC84?
Delete the members in the product group and then archive the product group in transaction SARA, object=MM_MATNR.
(The product group is created as a material master record with material type PROD and this record is deleted in SARA.)
